Three-time champion Ronnie O’Sullivan expects to be pushed all the way by 2010 Crucible winner Neil Robertson in the quarter-finals of the World Championship.

O’Sullivan beat Mark Williams 13-6 to reach the last eight and is now 15/8 with bet365 to clinch his fourth world title.
However, he said of Robertson, who is 7/2 to win the tournament: “I think whoever wins this championship will have to beat Neil Robertson, and I’ve got to play him now.
“Neil’s had a brilliant season, he’s won the Masters. He’s a big-time player and he’s proved it on the big stage.”
